Graphics Card Fan Connectors and Adapter Cables
At CRJ Electronics, we've documented and engineered the largest selection of computer fan adapter cables.
While graphics card fans may use connectors smaller than the 4-pin PWM fan specification published by Intel, they adhere to the same electrical specifications, including voltage, tachometer and PWM signal, and wiring sequence. This compatibility has simplified our process of reverse engineering each connector to offer fan adapter cables that allow expanded connectivity.
Users can thus maintain superior fan speed monitoring and control through their graphics card software for aftermarket heatsink installations and small form factor deshroud modifications.
⚠️ Attention
Graphics cards often use the same or similar connectors for LED lighting. Take note of this to avoid the possibility of damaging your hardware.
We highly encourage users to research their exact graphics card model and use resources such as the excellent teardown and PCB photos published by TechPowerUp.
PH Series 4-Pin Connector
The PH series connector, originally designed by JST, is the most common connector used on modern graphics cards.
It's use extends beyond graphics cards as Gigabyte small form factor ITX motherboards now feature this fan connector as well.
Due to its widespread adoption, we have developed several cables for this connector.
Single Fan Adapter
ViewDual Fan Adapter
ViewPH to 4-Pin Fan Header
For connecting PH 4-pin fans and water pumps to other fan headers. Useful for lowering pump noise in GPU AIO water cooled heatsinks
PH 4-Pin 12" Extension
An extension for PH 4-pin devices, useful in combination with our other PH adapters as well as with many other electronics devices
HY Series 4-Pin Connector
The HY series connector, a newer addition to the market, has higher power handling capabilities and a physical latch for more secure retention.
The HY-4A connector is used by EVGA on the majority of their RTX 3000 series graphics cards.
Note that the pin sequence is inverted compared to PH series connectors.
